## Discrepancy

ON FLIGHT 4469 DURING THE DESCENT THE CREW REPORTED THE LANDING GEAR WOULD NOT EXTEND AND RECEIVED A HYDRAULIC 1 LOW QUANTITY MESSAGE.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REPLACED THE DEFECTIVE HYDRAULIC LINE.  SERVICED THE RESERVOIR PER 12-13-01.  LEAK CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
